NEW YORK (CBSNewYork) — The man who provided crucial testimony in the sex abuse case against former Penn State assistant football coach Jerry Sandusky has broken his silence.

In an interview Tuesday with CBS News, Mike McQueary said his emotions were “all over the place, just kind of shaken” but refused to comment further on the case, saying “the whole process has to play out. I just don’t have anything else to say.”

McQueary testified before a grand jury that in 2002, he witnessed Sandusky raping a 10-year-old boy in a university locker room shower and reported it to then head coach Joe Paterno.

In an email written one week ago and obtained by the Associated Press, McQueary told a Penn State friend that he stopped the alleged assault and reported the abuse to police, but was criticized for coming forward.

“I am getting hammered for handling this the right way…or what I thought at the time was right,” he says in the email. “I had to make tough, impacting quick decisions.”

In the meantime, more alleged victims are coming forward. Pennsylvania attorney Ben Andreozzi says his client suffered years of abuse by Sandusky, whom he met through Sandusky’s charity the Second Mile.

“I believe he used that relationship with the Second Mile program and the university to his advantage so he could essentially stalk and prey on all his victims,” said Andreozzi.

Sandusky is out on bail, charged with molesting eight boys, although more victims have reportedly come forward.

Sandusky’s attorney claims there is at least one alleged victim who will deny any abuse took place.
